The Thi Lo Su Waterfall (Thai: น้ำตกทีลอซู, ;, also spelt as Thee Lor Sue, The Lor Sue, Thee Lor Sue or Te-law-zue;[1] lit: Black Waterfall[2]) is claimed to be the largest and highest waterfall in Thailand. It stands 250m (820feet) high and nearly 450m (1,480feet) wide on the Mae Klong River, flowing down from Huai Klotho into the Umphang Wildlife Sanctuary[3] in Tak Province in northwestern Thailand.[4]
The waterfall has apparently never been surveyed, so the figures given are approximate.[5]
Access to the waterfall campsite by private vehicles has been stopped. It is now only accessible via a cartel of pickups.Private vehicles have to be parked in Umphang.
